INKING MECHANISM.

'To all whomt may concern.'

Be it known that I, BRUCE C. WHITE, a citizen of the United States,residing at New York city, county of New York, and State of New York,have invented certain new and useful Improvements in lnkingl Mechanism,fully described and represented in the following specification and theaccompanying drawings, forming a part of the saine.

This invention relates to certain improvements in inking mechanism forprinting machines.

lt is one object of the invention to provide a construction of simpledesign for delivering a supply of ink to each column of the form carriedby the form member of a printing couple, the inking supplying devicesfor each column being independent so that the supply of ink to eachcolumn may be varied in accordance withthe matter in each column andthus eiect an even and regularv inking of the form and producing aprinted page of even and regular appearance.

It is a further object of the invention to provide a constructionwhereby the independent ink supplying devices may have the amount of inkdelivered thereto regulated or adjusted from a point outside themachine, so that the regulation or adjustment may be effected withoutinterrupting the operation of the machine, and in which preferably theink .is fed or delivered to the ink supplying devices under suchpressure as to secure certainty 'and uniformity in the ink supply.

With these and other objects in view, the

invention consists in certain constructions and improvements, a.detailed description of which will be given in connection with theaccompanying drawings, in which- Figurel is a yside elevation, partlybroken away, of so much of a printing machine as is necessary for anunderstanding of the .inventio-n; 4

there 4is provided a plurality of ink supplying devices by which ink issupplied for the form one such device preferably being provided for eachcolumn of the form, and these devices v'being independent of each otherso that the ink delivered by each may be varied `independently of theothers, and the ink ,is supplied to the form columns or sections underpressure and in-regular quan- A tities by separate pumps so that.thelinkis forced to the distributing cylinder or other ink-receiving memberwith certainty and uniformity. These ink supplyingxdevices may varysomewhat in their construction,

but in machines embodyin the invention in its preferred form theseevices will be in the form'of small delivery nozzles 7 suitably .mountedon the frame of the machine and having their delivery orifices arrangedside by side and in line, each delivery orifice being, as`shown, thewidthv of onecolumn of the form to which ink is to be supplied. Thesenozzles 7 may be of any suitable construction. As illustrated, thebottom wall of the nozzles is formed of a plate 8 bolted by flanges 9 toa cross frame 1() suitably secured in the machine. This bottom plate 8is common to` all the nozzles, and is of a length sufficient to providethe necessary number.

The plate 8 is illustrated curving upwardly, as indicated at 11, so asto deliver upwardly between the distributing cylinder 5 and roll 6. Theseparate nozzles are formed oncommon plate 8 by curved side walls 17which diverge from the rear sides of the nozzles, and cover plates 18,preferlably separate for access to the different nozzles. The side Walls17 carry nipples 13 lhaving inlet openings 14 communicating withindependent ink supply pipes,and are shown as secured to plate 8 byscrews 15 and the cover plates 18 are secured in position to plate 8 byscrews 19. As illustrated,

nozzles being connected with the source of' supply through independentconnections. .In machines embodying the invention in its preferred form,the ink is delivered from the main source of supply to the deliverynozzles or reservoirs under pressure, this being preferably accomplishedby providing a series of pumps, one for each nozzle, and in the bestconstructions means will be provided whereby the amount of ink deliveredby each pump may be varied. In order that this regulating and adjustingmeans may be` readily accessible, the supply reservoir or fountain islocated on the outside of the machine and has mounted therein the pumpsby which the ink is supplied. In the construction illustrated, thesupply fountain is marked 2O and is located on the outside of themachine, being supported on theframe by brackets 21. From the supplyfountain independent conduits, as pipes 22, lead to the deliverylnozzles. Each delivery nozzle is connected withits pipe in any suitablemanner to forni a tight joint, as by forming the end of the pipe 22 witha head 23 which abuts against the nipple 13 before'referred to,connection being made by athreaded union 2.4 taking over the head 23 andscrewing onto nipple 13. Located in the main fountain 20 are a pluralityof pumps, one pump being provided for each of the pipes 22 which aresecured to their respective pumps by means of suitable unions 25.

The particular type and construction of pump employed for delivering inkto the ink pipes may be widely varied, as may be the means for effectingadjustment or regulation of the ink delivered from each pump. Aconvenient construction, however, is that illustrated, in which thepumps are small vplunger pumps and -are driven through suitable devicesfrom` a common shaft. The construction of each pump is identical, andadescription of one will sufce for all. One of these pumps is illustratedin Fig. 3. In' the particular vconstruction there shown, the fountainhas Secured therein a casting 26 in which is formed a suction chambercontrolled by a ball valve 27 and a delivery controlled by a ball valve28, one of these being provided for each pump. The pump itself comprisesa frame 29 carrying at its lower end a plunger'30, the frame beingformed to provide above the plunger an abutment 31. This frame isreciprocated vertically to eect suction and delivery by means of aneccentric disk 32 carried on a driving shaft 33, the eccentric disks forall the pumps being carried on this shaft. The eccentric disk 32 on therotation of the shaft bears against the abutment 31 and causes theplunger to operate to deliver ink through the valve 28 controlling thedelivery chamber. In the particular construction illustrated, thedelivery stroke of the plunger is always the same. To provide forregulating the adjustment of the amount of ink delivered by each pump,means are provided for varying the suction stroke of the pump. lVhilethe means for effecting this may be somewhat varied, in the constructionillustrated there is provided a movable abutment which is in the form ofa screw 34 having at its lower end a head 35 and at its upper end amilled head 35 by which the screw may be adjiisted, this milled headbeing on the outside of the fountain. This screw 34 passes through theupper part of the 'frame 29, before referred to, and the head 35 isengaged by the eccentric disk 32, causing the pump to be lifted for the.suction stroke. It will be seen that by varying the position of head 35of the screw vertically with respect to the eccentric disk 32, the liftor Suction stroke of the pump will be varied,

and thus the quantity of ink` delivered by the pump at eachreciprocation thereof to vary. Furthermore, it will be observed thatwith the construction employed, the parts through which this adjustmentare obtained are conveniently located on the outside of the machine, sothat the desired adjustment can be made while the machine is running,and at the same time afford a very simple means for permitting anadjustment to be made quicklv.

The shaft.) 33 of the machine which operates the pumps may be driven inany suitable manner. In the particular construction illustrated, Where adistributing cylinder as 5 is employed, the shaft 33 may be driven fromthe cylinder shaft and in the best constructions the shaft will bedriven through frictional driving means, so that a very-nice degree ofadjustment as to the speed of the shaft may be obtained. In theparticular construction illustrated, the shaft 36`of the distributingcylinder 5 is provided beyond its journals With a friction disk 37 vWith Which coperates a friction Wheel 38 carried on a shaft 39 suitablyjournaled in hubs 40. This shaft is provided at one end With a Worm4lvwhich engages With a Worm- Wheel 42 on the end of shaft 33. Thefriction-Wheel 38,v before referred to, is keyed on the shaft 39 so asto have a movement along the same, whereby it maybe brought intodifferent driving positions With the disk 37 and its speed regulated toa great degree of nicety. rlhe friction-Wheel may be moved along theshaft 39 inany suitable manner. In the construction illustrated, thereis provided a nut 43 having yoke arms 44 Which take against hubs 45 onthe Wheel 38. This nut is operated by means of a threaded shaft 46journaled in hubs 47 and turned by means of a hand-Wheel 48. With thisconstruction it- Will be seen that by one adjustment the speed of allthe pumps mayA be varied simultaneously, and consequently the quantityof ink delivered by them may be varied likewise. At the same time eachpump may be adjusted independently of the gther's to vary the amount ofink delivered y it.

While 'the vconstruction illustrated vand described is one which iseffective for carrying out the invention, it Will be understood thatchanges and variations may be made in the arrangement of the deviceshown and described and that the invention is not to be limited to sucharrangement and construction.
